Description

  Embodiments relate to a radio communication system, a radio base station, an upper node, and a communication method.

  In recent wireless communication systems, in addition to existing wireless base stations, a small wireless base station called a “femto base station” is newly introduced to provide femto cell services. In the 3G (Third Generation) system, a radio base station is referred to as “NB (Node B)”, and a femto base station is referred to as “HNB (Home Node B)”. In the LTE (Long Term Evolution) system, the radio base station is referred to as “eNB (evolved Node B)”, and the femto base station is referred to as “HeNB (Home evolved Node B)”. Furthermore, when both HNB and HeNB are meant, it is called “H (e) NB”. Since H (e) NB can be installed in a home or a store, the installation location has a degree of freedom.

  Non-Patent Document 1 defines a service request for H (e) NB in 3GPP (Third Generation Partnership Project). According to Non-Patent Document 1, when installing a H (e) NB, a telecommunications carrier verifies identification information (identity) of the H (e) NB, and geographical location information of the H (e) NB ( There is a need to obtain a geometric location. In addition, telecommunications carriers should determine the installation and operation of H (e) NB to meet all relevant legal requirements.

  In addition, the specification of the interface between the HeNB and the HeNB-GW (Home evolved Node B Gateway) and the MME (Mobility Management Entity), which are upper nodes of the HeNB, is defined in Non-Patent Document 2 as S1AP (S1 Application Protocol). Has been.

  Non-Patent Document 2 does not stipulate a specific method for notifying HeNB identification information or HeNB geographical location information. For this reason, the upper node cannot obtain the HeNB identification information or the HeNB geographical location information.

  In addition, in order for telecommunications carriers to be able to determine the installation and operation of H (e) NB to meet all relevant legal requirements, H (e) NB is concerned with the surrounding environment. It is desirable to notify the upper node of information.

  In addition, there is a similar problem for a relay node (RN: Relay Node) having a function of relaying a radio base station. That is, since the RN may be a wireless network with a backhaul line, the position of the RN may move. Therefore, it is desirable that the communication carrier appropriately determines whether or not the RN can be installed and operated as in the case of H (e) NB.

  The problem described above is caused by the fact that the radio base station does not notify the upper node of the identification information and information about the surrounding environment. Accordingly, an object of the embodiment is to solve any of the above problems by providing a wireless communication system in which a wireless base station can notify an upper node of identification information and information about the surrounding environment. It is in. However, the embodiments can achieve objects other than those described above. Further, the embodiment is not required to achieve the above-described object, and does not have to achieve the above-described object.
